THE DIPLOMAT is the story of a man on a mission. J P (John Abraham) is the Deputy High Commissioner at the Indian High Commission, Islamabad, Pakistan. One day, a lady named Uzma Ahmed (Sadia Khateeb) arrives at the High Commission with her husband Tahir (Jagjeet Sandhu) and their family… friend Basheer (Bhawani Muzamil). When they are not around, Uzma straight away runs inside and asks for help. She claims that she has been forcefully married to Tahir and wants to fly back to India. The matter is serious and hence, J P takes cognizance. He wants to help Uzma but fears that she might have some ulterior motives. He cross-checks all her claims and when he realizes she’s speaking the truth, he decides to ensure that she returns safely to their homeland. But the challenges are immense. Even if they get all the official help, the hostile elements of Pakistan can prove to be detrimental. What happens next forms the rest of the film.
